Subject: RUBY_IMPLEMENTATION

Hi,

I met with Wayne Kelly (of Ruby.NET) at the JAOO RubyFools
conference.  That means I have met all primary developers of all major
Ruby implementations.  Yay.

He asked me how we can distinguish the implementation from program.
Currently RUBY_PLATFORM gives you the platform the implementation is
on.  RUBY_VERSION gives you the version but it is the language
version.   Probably we need to introduce a new constant to represent
the implementation of the running VM.

What do you think the constant name should be?
RUBY_IMPLEMENTATION?  Too long?
